16 Read the contents of the specified tile into the (user supplied) data
17 buffer. Note that the value of tile is a ``raw tile number.'' That is,
18 the caller must take into account whether or not the data is organized
19 in separate planes (PlanarConfiguration=2). TIFFComputeTile automatiā
20 cally does this when converting an (x,y,z,sample) coordinate quadruple
21 to a tile number. To read a full tile of data the data buffer should
22 typically be at least as large as the value returned by TIFFTileSize.
23
25 The actual number of bytes of data that were placed in buf is returned;
26 TIFFReadEncodedTile returns -1 if an error was encountered.
27
29 All error messages are directed to the TIFFError(3TIFF) routine.
